TST: Update Fama French Test for changes to CRSP

See: http://mba.tuck.dartmouth.edu/pages/faculty/ken.french/Data_Library/changes_crsp.html

Please note: CRSP has recently completed the Pre62 Daily Data Series Project. The addition of these new daily data results in changes to month-end prices and to dividend ex-dates. These changes have resulted in many small changes to historical returns on my website.
